As it came up in a different thread a few weeks back, Hybrids are in kind of an awkward place right now.
The original special things they did (pinpoint smart attacks and organized defense) have been taken over by the Threatfleet and Special Forces. That leaves only the Advance Hybrid special Plot interaction as their unique thing (aside from the units themselves, of course). I have some ideas about normal Hybrid stuff, but for this thread, I just want to discuss the Advanced Hybrid Plots that are so exciting.
Right now, there is only one Hybrid - Plot interaction: The Dyson Sphere. I propose that the Hybrids should have AT LEAST one interaction with every single other plot and minor factor where it is reasonable, plus a number of other, base generic plots that don't rely on other AI Plots or factions being enabled. There could even be special Hybrid - AI Type interactions.
For example, a generic plot might be a structure that hides Wave Warnings, or adds a Lesser Avenger Module to the Command Station on some random AI system.
A Plot interaction might be something like being able to redirect the Devourer to Human territory, or upgrading the Shark penalties. Or, if there's an Astro Train rework, some of the nastier side like the Superfortress Construction project could become Hybrid plots ("An Advanced Hybrid is using the Astro Train system to supply a massive construction project!").
What other sorts of interactions do people think would be interesting? Remember that each needs to be something that make the AI more threatening, potentially even game-endingly so in the final stage, but capable of being stopped partway. I don't think there's a need for every plot to be multi-stage, or amazingly powerful - even just annoying would be good enough.
Here are some of the ideas I've come up with:
Generic
Upgrade planet levels
Build Trader Goodies
Anti-Neinzul BotNet weapon/module/Guardpost (for countering overuse of those units)
Build AI Specific unique stuff (planet cloaker, IP Munition Booster, etc)
Hide Wave Warnings
Cross-planet Waves
Build Avenger / Lesser Avenger modules
Become schizophrenic
Create Nuclear Command Stations (or other non-planet-killing Nuke device - Nuke Alarm?)
Hybrid <-> Plot interactions:
Beachhead - Beachheads need a rework first.
Hunter - Increase special units added to Hunter; Target special Hunter fleet at specific Human special units, and follow anywhere it goes;
Shark-A -
Shark-B -
Preemption -
Counter-Posts - Build them anywhere at all
Astro Train - Construction Projects (lots of ideas)
Warp Relay - Upgrade range, frequency, convert to Backdoor Hacker-like Exogalactic Wormhole on HW?
Hybrid <-> Minor Faction interactions:
Human Resistance - Prevent from spawning, or spawn in bad locations; Sometimes attacks Human player instead of AI (AI hacks their IFF);
Human Marauders - Bait into more attacks; use as Mercenary ships for AI Hybrid escorts;
Human Colony - Setup 'Trap' colonies that when freed spawn a horde of AI units; produce an anti-colony device that hunts them down through Cloaking;
Zenith Trader - Buy stuff from Zenith Traitor;
Zenith Miners -
Dyson Sphere - Antagonizer / Antagonizer 2 / BOOM; Antagonizer / Additional drone types / Teleporting drone waves;
Zenith Devourer - redirection, friendly, upgrade to attack non-mobile
Broken Golems - Repair and use the Golems themselves
Botnet Golem -
Neinzul Rocketry Corp - Increase rate of fire and variety of types (no AIP gain);
Neinzul Preservation Wardens -
Neinzul Wandering Enclaves -
Fallen Spire - Can conduct Shard surveys (not Core) to find and kill Shards first? Maybe just fortify the system, or allow for alternate Shards to be found in those cases;
Spire Civilian Leaders - Hybrid Slavemaster Module increase AIP gains; recaptures 'freed' but not Human held SCLs;
Spirecraft - Build Spirecraft to be Hybrid drones; Build new asteroids to then build Spirecraft from; plant fake asteroid traps - mine one, get a BOOM;
Dark Spire -
Alt-Champion Progress/Nemesis - Can acquire units/Starbases of hostile factions?
Showdown - Try to recapture before Showdown activates? Build additional devices to be captured? Fortify AI held devices heavier?
Nomad - Direct Nomads to locations to bypass Human fortifications (Human to AI, AI to Human HW); Activate Beacon?
